Adjust Ring Gear Position (Backlash)

If the ring gear pattern shows incorrect face width contact,

change backlash by

adjusting the ring gear.

If the pattern is too close to the edge of the tooth toe, move the

ring

gear away from the pinion to increase backlash.

1. Loosen the bearing adjuster on the teeth side of the

ring

gear several notches.

2. Loosen the opposite adjuster one notch.

3. Return to adjuster on teeth

side of the ring gear and

tighten adjuster until it contacts the bearing cup.

4. Continue tightening the same adjuster two (2) or

three (3) notches

and recheck backlash.

If the pattern is concentrated at the heel (too far up the tooth),

move

the ring gear toward the pinion to decrease backlash.

5. Loosen the bearing adjuster on the teeth side of the

ring

gear several notches.

6. Tighten the opposite adjuster one notch.

7. Return to adjuster on teeth side of ring gear and

tighten adjuster until it contacts the bearing cup.

8. Continue tightening the same adjuster two (2) or

three (3) notches

and recheck backlash.
